As with 1 Chronicles, this seems to mostly be a rehash of events we already heard about. This time the stories being retold are from 1 Kings.
Most of the chapter surrounds Solomon’s request for wisdom that was also featured in 1 Kings 3. It’s worded a little different, but the sentiment is basically the same.
The following chapters are parallel accounts of what happens with Solomon in 1 Kings
Here’s how the chapters correspond:
2 Chron 6 to most of the rest of 1 Kings 8
2 Chron 8 to the rest of 1 Kings 9
2 Chron 9 to 1 Kings 10 but then skips the events of 1 Kings 11 and goes right to Solomon’s death at the end of the eleventh chapter. That means that this account excludes Solomon’s wives and the blame that is set upon them for Solomon turning away from God and the subsequent rise of his enemies by God because of this.
There’s another interesting difference between 2 Chronicles 9 and 1 Kings 10. When he dies, there is a mention of where other accounts can be found but neither book mentions the other. Here is what each once says:
Now the rest of the acts of Solomon, and all that he did, and his wisdom, are they not written in the Book of the Acts of Solomon?
That’s from 1 Kings 10. There is no Book of the Acts of Solomon in the Old Testament. Here’s 2 Chronicles 9:
Now the rest of the acts of Solomon, from first to last, are they not written in the history of Nathan the prophet, and in the prophecy of Ahijah the Shilonite, and in the visions of Iddo the seer concerning Jeroboam the son of Nebat?
Of course, none of these people wrote books of the Old Testament either, so that doesn’t help much, but Nathan is mentioned several times in 1 Kings as well as Ahijah but Iddo is new. I did a search for the name. There appears to be someone who bears this name in Ezra and Nehemiah later, but they don’t seem to be contemporaries of Solomon, so maybe he’s a different Iddo. The study section of my Bible doesn’t have much to say about it but I just thought it was interesting to point out.
